MACHINE FOR SCOURING AND CLEANING GRAIN.

SPECIFICATION forming part of Letters Patent No. 319,909, dated June 9,1885. Application filed February 5, 1885. (No model.) Patented in England November '7, 1884, No. 14,727.

To all whom it may concern:

Be it known that I, Tnomxs INeLIs, a subject of the Queen of Great Britain and Ireland, and a resident of Leith, Scotland, have invented a Machine for Securing and Cleaning Grain, (for which I have obtained a British Patent, No. 14,727, dated November 7, 1881,) of which the following is a specification.

This invention relates to certain improvements in a machine for scouring and cleaning grain by means of friction between disks having V -shaped concentric grooves and ribbed surfaces, brushes, and a fan for drawing away the dust and dirt.

-I carry my invention into practice in the following manner, which I will now describe by aid of the accompanying drawings, in which- Figure 1 is a sectional elevation, and Fig. 2 is a half elevation, of the front with pulley removed and a half elevation of the back end of the machine.

Like letters indicate like parts in these figures.

I employ a steel, iron, or chilled-iron disk, A, grooved with V-shaped concentric grooves G, and having rounded radial ribs Don its surface, said disk being caused to rotate on a shaft, S, carried in suitable hearings in close proximity to a stationary disk, B, grooved and ribbed in like manner, but fixed to the framing of the machine. The distance be tween the surfaces of the disks B and A is capable of adjustment, as required, by ordinary means. The raised portions of the disk A are made to project into the recessed portions of the disk B, a sufficient space being left for the passage of the grain under the necessary friction.

The grain is supplied at or near to the center of the stationary disk B by a suitable feedspout, E, and passes between the disks A and B to their peripheries and into a casing covered with wire-cloth F, through which the dirt escapes into a hopper, G, and is led into a sack or suitable receptacle. The grain is not allowed to discharge freely from the disks, but is retarded by its filling the casing.

dischargespout, H, is placed at the top of this casing, through which the grain passes in its discharge from the disks, thus giving the necessary pressure without breaking the grain, the object being to cause the particles of grain to scour each other. the above-mentioned spout H into the center of a stationary circular brush, K, fixed to the framing of the machine, and is polished by a rotary circular brush, L, also mounted on the shaft S. The distances between the brushes K and Lare also adjustable by ordinary means, a set-screw, a, being shown. The grain, after passing between and from the brushes K and L, falls into a hopper or spout, M, where it is subjected to the action of an ordinary. exhausting-fan, N, fixed on the shaft S,with regulating air-valve O, by means of which the dust and dirt are drawn away and discharged into a dust-room. The wheat from the brushes falls into the spout P from hopper M and passes from thence, as usual, to an elevator. The said spout is provided with an air-inlet, b, and the dust is drawn from the wheat by the fan N through hopper Q, while the smali wheat falls into the bottom of the hopper, from whence it may be transferred to a sack, all as indicated by arrows in Fig. l. The dust escapes from the fan through exit T.

The valve 0 is one of ordinary construction, and extends from one end to the other The grain passes down 7 of air-trunk U of the fan, and turns on pivots at its two ends, so as to more or less close the trunk, all as usual, and as is well understood.

The whole is inclosed in a suitable casing or framing, V, as shown. I do not confine myself to the employment of one pair of disks, but may use two or more on the same spindle, according to the degree of securing required to be done, the grain being led from the top of the casing of one pair to the center of the.
